help please :(

*UPDATE: I am worried about how light the positive line compared to the negative line. Does it matter that they are different shades? I will be retesting in a few days to double check. 
This  is my first time taking a pregnancy test. Can someone help me by telling me if it's a postive or negative? It looks positive but the negative line is a little darker than the positive. I am only a day late with my period and it usually comes like clock work.   I am keeping my fingers crossed it is positive.... thank you!
